CVE-2021-20203 [LOW] CWE-190 CVE-2021-20203: An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2. An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2.0. It may occur if a guest was to supply invalid values for rx/tx queue size or other NIC parameters. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.

CVE-2020-11987 [HIGH] CWE-20 CVE-2020-11987: Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the NodePickerPanel. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.

CVE-2021-26120 [CRITICAL] CWE-94 CVE-2021-26120: Smarty before 3.1.39 allows code injection via an unexpected function name after a {function name= s Smarty before 3.1.39 allows code injection via an unexpected function name after a {function name= substring.

CVE-2021-26119 [HIGH] CVE-2021-26119: Smarty before 3.1.39 allows a Sandbox Escape because $smarty.template_object can be accessed in sand Smarty before 3.1.39 allows a Sandbox Escape because $smarty.template_object can be accessed in sandbox mode.

CVE-2021-27379 [HIGH] CVE-2021-27379: An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unin An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unintended read/write DMA access, and possibly cause a denial of service (host OS crash) or gain privileges. This occurs because a backport missed a flush, and thus IOMMU updates were not always correct. NOTE: this issue exists because of an incomplete fix for CVE-

CVE-2021-26720 [HIGH] CWE-59 CVE-2021-26720: avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/net avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE

CVE-2021-26930 [HIGH] CVE-2021-26930: An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service request An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, an

CVE-2020-8625 [HIGH] CWE-120 CVE-2020-8625: BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TS BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration option

CVE-2021-26931 [MEDIUM] CWE-770 CVE-2021-26931: An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations p
